[Abstract]:With the application of IEC61850 standard, the operation level of intelligent substation moves to a higher level. In intelligent substation, the secondary circuit is changed from hard wiring mode to virtual circuit mode, and many problems of the original secondary circuit are solved by process layer information sharing. However, the current practice of intelligent substation is mainly focused on the technical research of new devices and unified message specification. However, there is a lack of research on the influence of the operation and maintenance mode of intelligent substation under the new mode and the control scheme of the whole process. As a result, the current intelligent substation can not fundamentally bring substation operation and maintenance, safety and economic aspects of the real changes, this is the restriction of the current intelligent substation is only in the "pilot" link of the fundamental problem. In view of the characteristics of canceling hard cable loop in intelligent substation, the key techniques of secondary equipment operation and maintenance, such as secondary virtual loop state monitoring and SCD file control, are deeply discussed and studied in this paper. This paper first analyzes the present situation of intelligent substation operation and maintenance at home and abroad, and points out the problems existing in the operation and maintenance mode of substation at present. On this basis, the main contents and methods of this research and the significance of the research are put forward. Then the basic structure of intelligent substation is expounded, and the system of secondary equipment operation and maintenance is analyzed according to the structure and function of intelligent substation. Based on the study of the network form of the secondary virtual link, the visual monitoring and the mapping relationship between the physical link topology and the virtual link of the secondary loop, the method of modeling and topology identification of the virtual and real circuit of the secondary equipment is used. It provides the data basis for the design of the secondary virtual loop state monitoring system. Then, on the basis of a large number of key information (including substation primary equipment model and electrical topology information, function view, communication view, product view, data flow, etc.) recorded in the SCD file, which are related to the safe and stable operation of the intelligent substation, and so on. According to the SCD file control method of intelligent substation secondary virtual loop integrated configuration, the application analysis is carried out in combination with the actual model. Finally, the virtual loop state monitoring and SCD file control system of secondary equipment is tested by the substation configuration file in the field. The test results show that the system can realize the visualization of communication configuration process in intelligent substation.
